About this driver

The SB Acoustics SATORI MR13PNW-4 is a woofer with a free-air resonance of 41 Hz and a total Q (Qts) of 0.23. Its efficiency-bandwidth product (EBP) of 164 points toward a ported alignment. See the sealed vs ported guide for how to choose.

modeled estimate

These tweeters could pair with the SB Acoustics SATORI MR13PNW-4 in a two-way design, but the seed Thiele/Small data is too thin to grade the match yet — add or measure T/S (Fs, Sd, Xmax) to compute a real compatibility grade. You can still open a pair in the guided builder.

Modeled estimate from T/S + geometry — no measurements. The verdict is robust; it improves with measured FRD/ZMA data.
